Title: Coin accumulation returning device
Inventor: EDA SHIGEHIRO
IPC: G07F9/00
Filed: 1988-12-14
Abstract: PURPOSE:To allow an arriving coin to direct in one direction and to eliminate the jam of coins by successively driving only the return levers of individual accumulation parts accumulated with coins upward in one row and then upward in the other row. CONSTITUTION:When coin returning processing is started, a main CPU 11 decides whether a coin to be returned exists in a coil storage returning lever positioned on the lowermost position or not by an accumulation sensor control part 12. When a coin to be returned exists in the right side lever, the coin is successively upward returned. When a coin to be returned exists in the left side lever, the coin is also successively upward returned. Since the coin arriving at the vicinity of a return outlet is allowed to direct always in one direction, the coin does not collide with another one in the vicinity of the return outlet.

When the signals pass through the half of one track in the A head, the D head starts recording. Afterwards, when the B and C heads successively execute the recording operation, two video signals can be alternatively recorded to one tape. At the time of reproducing, a control track signal on the tape is detected and two-picture recording is decided. Then, the A head detects the A track and the D head detects the D track. In such a way, the signals are reproduced. Thus, the two video signals can be simultaneously recorded and reproduced.

Abstract: PROBLEM TO BE SOLVED: To provide an etching apparatus which prevents that a deposited substance of reactive product by the etching is formed on a focus ring and can reduce a program and a method of manufacturing semiconductor device using the same etching apparatus. SOLUTION: In an etching apparatus 11 comprising an upper electrode 2 and a lower electrode 3 provided opposed with each other and a focus ring 4 placing an etching object 5 on this lower electrode 3 and surrounding the etching area 10, a focus ring 4 is formed of SiC.

Abstract: PURPOSE:To stabilize phase locked loop control by providing a first measuring means to measure phase difference between a frequency reference signal and an output pulse signal, and a second measuring means to measure the frequency change rate of the frequency reference signal, and controlling the output pulse signal corresponding to both measured results. CONSTITUTION:In an ordinary operation, such control is performed that the phase difference between an input signal f0 and an output signal f1 can go to zero with a microprocessor 23 and a preset counter 24 based on the phase difference output data of a first timer 21. When it is detected that the frequency change rate exceeds a prescribed value with the input frequency measured data of a second timer 22, such control that phase locked loop control for the input signal based on the output data of the first timer 21 is evaded and an output frequency before fluctuation can be held is performed. Thereby, the phase locked loop control without generating rapid change of the output frequency can be performed. Therefore, no rapid change of the output pulse signal occurs even when the frequency of the frequency reference signal changes steeply, and also, adjustment can be easily performed.
